67 62... Notes on initializing power windows
NOTE:
Initialization
is performed on the power window switch of the relevant door.
Initialization comprises:
With normalization, the mechanical end stops of the power window regulator are recorded and stored.
The characteristic curve is learnt immediately after normalization.
When the characteristic curve is learnt, the mechanical closing forces of the power windows are recorded and stored for correct operation of the anti-trapping mechanism.
Initialization, i.e. normalization and learning of characteristic curve, is performed in a continuous operation.
